IMPROVEMENT IN SAXFETV WHIFFLETREES.

Specification forming part of Letters Patent No. 122,394, dated January 2, 1872.

Specification describinga new and Improved Safety Whiffletree, invented by ALBERT H. MCALLISTER, of Cotton Plant, in the county of Tippah and State of Mississippi.

The object of this invention is to provide ready and convenient means for liberating'a horse or horses from a carriage or other. vehicle while the horse is in motion and it consists in the construction of the trace-hooks and in two-liberating levers attached to the whiffletree, and in the construction, arrangement, and combination of parts, as hereinafter more fully described.

In the accompanying drawing, Figure lrepresents a top view of a Whiffletree provided with my detaching apparatus partly in section. Fig. 2 is aview, showing the back edge of the whiffletree and the manner in which the levers are made to engage with the trace-hooks. Fig. 3 is an enlarged view of one end, looking from the line :0 .r of Fig. 1. Fig. at is a perspective view of the trace-hook with a portion of the trace.

Similar letters of reference indicate correspondin g parts.

. A is the'whifl'letree. B B are thecuff-irons on the ends thereof. These irons extend beyond the ends of the whiffletree, so that there are recesses to receive the trace-hooks, as seen in Fig. l. O is the trace-hook. Dis a bit, and E is a guide-pin on the end. The cuffs B B have each a plate, F, which is bentat right an gles with the ends, as seenin Fig. 1. Through this plate is a hole for the pin E. G G are iron plates on the endsof the whiftietree, within the cuffs B B. H H represent the beveled corners of the whiffletree'.. I I are the two tripping-levers, Whose fulorums are at the points J J. K K are springs which bear against the short ends of the levers'with a constant pressthose plates, which will liberate thetraces from the whiffletree. The springs K K keep the levers I I in position, and securely confine the traces when everything is all right, but if anything breaks and the horse or horses become unruly, and danger is apprehended, all the driver has to do is to pull the cord and let the horse or team go.

I do not confine myself to the particular form orarrzmgement of any of the parts described, as they may be varied in many ways-without departing from my invention.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patcut- 1. I11 combination with a Whiffletree, the trippingelevers I I, springs K K, and cord M and bit D of the trace-hook, substantially as and for the purposes described.

2. The bit D, in combination with a tracehook, as and for the purposes described.

3. The guide-pin E on a trace-hook, as and for the purposes described.

4. The cuff-irons B B, in combination with the trace-hook O and whiffletree A, when said irons are constructed and arranged on said whiffletree, as shown and described. I
